Lamp or display comprising at least one light panel on a carrier plate

Abstract

A lamp or display is comprised of at least one light panel ( 10 ) on a carrier plate ( 13 ) comprising at least one light panel ( 10 ) in the form of an OLED illuminant, lying on or against an at least partially light-permeable carrier plate ( 13 ) of the lamp in a planar manner. A liquid or viscous medium ( 11 ) is arranged between the adjacent surfaces of the light panel ( 10 ) and of the light-permeable carrier plate ( 13 ), and the connection between the light panel ( 10 ) and the carrier plate is an adhesive connection, which can be easily undone without destroying or adversely affecting the carrier plate ( 13 ).

The invention claimed is: 
     
       1. A lamp or display comprising at least one light panel ( 10 ) on a carrier plate ( 13 ) comprising at least one light panel ( 10 ) in the form of an OLED (organic light-emitting diode) illuminant, lying on or against an at least partially light-permeable carrier plate ( 13 ) of the lamp in a planar manner, characterised in that a liquid or viscous medium ( 11 ) is arranged between the adjacent surfaces of the light panel ( 10 ) and of the light-permeable carrier plate ( 13 ) and in that the connection between the light panel ( 10 ) and the carrier plate is an adhesive connection, which is easily undone without destroying or adversely affecting the carrier plate ( 13 ). 
     
     
       2. The lamp or display according to  claim 1 , characterised in that the adhesive medium ( 11 ) has a refractive index deviating only slightly from glass, in particular a refractive index within a range of approximately 1.3 to approximately 1.6. 
     
     
       3. The lamp or display according to  claim 1 , characterised in that the adhesive medium ( 11 ) comprises or is a substantially colourless and/or clear liquid with a dynamic viscosity at ambient temperature of about 50 to about 10 5  mPas. 
     
     
       4. The lamp or display according to  claim 1 , characterised in that the adhesive medium ( 11 ) comprises or is an organic liquid, in particular selected from the group comprising alcohols, multi-valent alcohols, hydrocarbons, hydrocarbon mixtures, oils, fats, ketones, aldehydes and esters as well as mixtures therefrom. 
     
     
       5. The lamp or display according to  claim 1 , characterised in that the adhesive medium ( 11 ) contains or is an organic material selected from the group of low-viscosity paraffin, high-viscosity paraffin, Vaseline, petroleum, glycerine, glycol, cyclohexanone, silicone oil, siloxanes as well as mixtures therefrom. 
     
     
       6. The lamp or display according to  claim 1 , characterised in that the light-permeable carrier plate ( 13 ) facing the light panel ( 10 ) and to be separably connected therewith consists, as required, of coated glass or plastic glass, in particular acrylic glass. 
     
     
       7. The lamp or display according to  claim 1 , characterised in that the carrier layer of the light panel ( 10 ) facing the light-permeable carrier plate ( 13 ) and to be separably connected therewith consists, as required, of coated glass or plastic glass, in particular acrylic glass. 
     
     
       8. The lamp or display according to  claim 1 , characterised in that the light panel ( 10 ) comprises a LED illuminant or light-emitting micro-lens array or a display surface provided for the reproduction of stationary or moving images. 
     
     
       9. The lamp or display according to  claim 1 , characterised in that this lamp or display is an external light, an internal light, in particular a pendant light, hanging light, ceiling-mounted light, ceiling-recessed light, standing light, wall light or table light, or is a lighting shelf or lighting panel or part of a furniture item or urban space furniture item or a facade element, wall element, ceiling element, an external light of a motor vehicle or a fitting in a motor vehicle, rail vehicle, ship or aeroplane. 
     
     
       10. The lamp or display according to  claim 1 , characterised in that a number of light panels ( 10 ) are arranged in one or more rows on one side of an at least partially light-permeable carrier plate ( 13 ). 
     
     
       11. The lamp or display according to  claim 1 , characterised in that dispersed diffuser particles are contained in the adhesive medium ( 11 ), which cause an optical scattering of light passing through the array. 
     
     
       12. The lamp or display according to  claim 1 , characterised in that a colorant is contained in the adhesive medium ( 11 ). 
     
     
       13. The lamp or display according to  claim 12 , characterised in that the colorant comprises colour particles dispersed in the adhesive medium ( 11 ), in particular colour pigments, in particular fluorescent pigments. 
     
     
       14. The lamp or display according to  claim 12 , characterised in that the colorant comprises at least one colouring agent dissolved in the adhesive medium ( 11 ). 
     
     
       15. A lamp or display comprising at least one light panel ( 10 ) in the form of a OLED (organic light-emitting diode) illuminant, lying on or against an at least partially light-permeable carrier plate ( 13 ) of the display in a planar manner, characterised in that a paste-like, gel-like or gelatinous adhesive medium ( 11 ) is arranged between the adjacent surfaces of light panel ( 10 ) and light-permeable carrier plate ( 13 ) and in that the connection between the light panel ( 10 ) and the carrier plate is an adhesive connection, which is undone without destroying or adversely affecting the light panel ( 10 ) or the carrier plate ( 13 ).
